OVERALL-LOOP Filed Feb. 27, 1951 Patented Dec. 13, 1932 Nrran STATES PATENT; OFFICE CHARLES A. ivrosenovn, or WATERBURY, CONNECTICUT, Assienoa To THE Antwan COMPANY, mo or oAKvILLn, CONNECTICUT, A CORPORATION or CONNEQTICUT OVERALL LOOP Application fiIed February 27, 193i. Serial No; 518,625.

This invention relates to new and useful improvements in loop fasteners or securing means such as are used for connecting the shoulder straps of overalls to buttons on the upper corner portions of the overall bib and comprises improvements in that form of loop fastener shown in my application Serial No. 451,624, filed May 12, 1930.

An object of the invention is to provide a ,loop fastener including relatively movable arms and means to prevent said arms from moving apart on a strain being placed on the loop as for example when parts connected by the loop attempt to pull away from each other! A further object is to provide a loop fastener as stated and which is simple in construction and which may be manufactured cheaply and in quantitieswhereby to sell at a reasonably low cost.

Other objects and advantages will become apparent from a consideration of the following description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. I-Iowever,it is to be understood that the invention is not limited to the details shown and described but comprehends all such variations and modifications as fall within the spirit of the invention or the scope of the appended claims to which claims reference must be had for a definition of the invention.

In the drawing:

Fig. 1 isa front elevational View showing portions of an overall bib and strap with the loop fastener of the invention connecting them;

Fig. 2 is a similar view showing the parts inthe relative relationship occupied by them when the fastener is but partially applied or partially removed;

Fig. 3 is an enlarged View showing the lower or locked portion of the improved loop fastener; and

Fig. 4 is a sectional view on theline 44 of Fig; 3-.

Referring in detail to the drawing, at 5 is shown a portion of the shoulder strap of an overall to which the loop fastener of the invention is attached. This loop fastener which in its entirety is designated 6 is adapted tobe passed over a button 7 having a shank 8, for securing the strap to the overall bib carrying the button, a portion of the bib being shown at 9.

As herein shown the improved loop fastener generally designated 6 is formed from a' single length of metal, preferably from a single length of round wire. Loop or fastener 6 includes a top or attaching bar or portion 10 about which theend of the strap 5 is carried to secure the fastener to the strap.

From the drawing, it will be seen that the length of wire forming the loop fastener 6 is bent at spaced points intermediate its ends as at 11 and 12 whereby to form the attaching bar 10. These bends 11 and 12 are preferably in the form of short arcs, the side arms or bars 13 and 14 of the loop being then carried toward each other and bent upon themselves as at 15 forming with the attaching bar 10 a partially closed loop or eye 16 for the reception of the shoulder strap 5.

From the bends 15 the arms 13 and 14 curve outwardly from each other and then inwardly toward each other to provide a; relatively large eye 17 and a restrictive or narrow neck 18 at the lower end of said eye. At the neck 18 the side arms 13 and 14 are again bent outwardly at anincline to form the sides 19 I of a relatively small eye 20 the lower end of which is closed by bending the end portions of the arms at sharp anglesasat 21 and 22, disposing the end portions 23 and 24 in overlapping relationship.

As herein disclosed the bend 21 of' the end portion 23 of the arm 13 is such as to dispose said end portion in a plane above the end portion 24 of the arm 14. The extreme end of the portion 23 is curved downwardly and looped around the portion 24 forming an eyelet 25 in which the end portion 24 is slidably received. To prevent portions 23 and 24 from: moving out of overlapping relationship the extreme end of portion 24 is upset or headed as at 26, head 26 being of sufficient diameter to prevent the pulling of the portion 24 through the eyelet 25. a

The improved loop fastener 6 includes means to prevent the arms13 and 14 moving apart when a strain is placed on the'loop due to a pull between two parts which may be connected by the loop. For example, such a strain might occur between the overall shoulder strap 5 and the bib 9 of the overall. Should such a pull or strain occur and should the arms 13 and 14 move apart the eye 20 would become enlarged and release the button 7 and it is to prevent the possibility of such casual release that I have provided locking means. 7

To prevent casual separation or moving apart of the arms 13 and 14 when the loop is subject to a strain I have notched the end portion 24 of the arm 14 as at 27 whereby to provide a shoulder 28. The eyelet 25 includes a portion 29 normally disposed in the notch 27 and a surface of the eyelet may, if desired, be flattened as at 30 and this flattened portion disposed in the notch27'. WVith this construction it will be obvious that with the fastener secured as to the strap 5 and with the shank of the button 7 disposed in the eye 20 should a strain be placed on the fastener, the pull of the fastener on the shank of the button will tend to depress the end portion 23 of the arm 13 of the fastener as indicated by arrow 31 whereby topress the portion 29 of the eyelet 25 against the bottom of the notch or recess 27. Now, any tendency of the arm to move apart will simply result in port-ion 29 of the eyelet being 'forced against the shoulder 27 and the arms 13 and 14 will be unable to separate. In other words the armsare locked against separation and the greater the pull the more securely will they be locked.

When it is desired to secure the strap 5' to the button 7 loop 6 is passed over the head of the button, the size of the eye 17 permitting this. Next the strap is pulled upwardly to cause the shank of the button to press against the portions of the arms 13 and 14 forming the neck 18 whereby the arms will be spread apart, the arms not being locked because there is no downward pull on horizontal member 23. The button will have its shank disposed in the eye 20 after passing through the neck 18. With the button thus disposed its flange will extend over the portions 19, 23 and 24 of the loop 6 as best shown in Fig. 1.

It is to prevent the arms 13 and 14 from moving apart to that extent necessary in order that the eye 20 might be enlarged to permit the passage of the head of the but-ton that I have provided the locking means above described. Obviously, any strain on the device will simply press the portion 29 of the 'fore, this strain will not enlarge the eye to the extent necessary in order that the flange of the button ma pass through it but the greater the strain the more securel will it be locked.

Further, it is to be noted that the side bars of each of the eyes 17 and 20 incline toward the restricted neck 18 whereby to guide the button shank toward this neck either in attaching the improved loop fastener to a button or in removing it therefrom. It will be understood that in attaching the loop 6 to a button it is simply necessary to insert the button through the eye 17 and then to pull the loop since the shank of the button will force the arms 13 and 14 apart to permit passage of the shank through the neck 18 into the eye 20.

It will also be understood that when removing the loop fastener 6 from a button the loop may be pressed in the direction of the button or the button may be pressed in the direction of the neck 18. In either event the shank of the button will force the arms or bars 13 and 14 of the loop apart whereby to permit the passage of the shank through the neck 18 to dispose the button in the eye 17 from which it may readily be removed. This is possible because the members 23 are not locked where there is no strain of the button on member 23, but the resiliency of the wire holds portion 29 in the notch 27 with sufficient force to prevent accidental separation.

Having thus set forth the nature of my invention, what I claim is: 1

1. A loop fastener of the class described including an attaching portion and a pair of relatively movable arms having a normal position with respect to one another, normally ineffective locking means for securing said arms against movement away from one another beyond their normal positions, and said locking means arranged in such a manner as to be made immediately effective to secure said arms in their normal position by a strain placed on the loop.

' 2. A loop of the class described including an attaching portion, a pair of arms extending from the attaching portion, said arms having their end portions bent into overlapping relationship whereby to close the loop, locking means on the overlapping end portions of the arms, saidlocking means being arranged in such a manner as to be nor mally ineffective and to be made effective to secure the arms in normal position and prevent spreading of the arms in a manner to enlarge the loop on a strain being placed on the loop.

3. A loop of the class described including an attaching portion, a pair of arms extending from said portion, said arms bent to provide a relatively large and a relatively small eye connected by a restricted portion, said arms at their end portions bent into overlapping relationship and disposed one above the other and in the same plane whereby to close one side of the relatively small eye, and one of said end portions having a notch and the other of said end portions having a portion adapted to enter said notch, said notch and portion being arranged on the end portions in such a manner as to secure the arms in normal position and prevent the spreading apart of the arms and the enlarging of the small eye upon a strain being placed on the loop.

l. A loop of the class described including an attaching portion, a pair of spaced arms extending from the attaching portion and the ends of said arms extending toward each other and arranged in overlapping relationship and slidably connected together in such a manner whereby the arms may be sprung apart without opening the loop, the overlapping portion of one of said arms having a notch spaced from the end thereof and the overlapping portion of the other arm having a portion normally in alignment with but removed from said notch adapted to be moved into said notch to secure the arms in normal position and prevent the arms being forced apart on a strain being placed on the loop.

5. A loop of the class described including an attaching portion, a pair of spaced arms extending from the attaching portion and the ends of said arms extending toward each other and arranged in overlapping relation but in the same plane and in the plane of the arms slidably connected together in such a manner whereby the arms may be spread apart without opening the loop, the overlapping portion of one of said arms having a notch spaced from the end thereof and the overlapping portion of the other arm having a portion normally in alignment with said notch but removed therefrom adapted to move into said notch to secure the arms in normal position and prevent the arms being forced apart on a strain being placed on the loop.

6. A loop of the class described comprising an attaching bar, a pair of arms extending from said bar and bent inwardly thereunder to form a partially closed loop, said arms then curved outwardly and downwardly and then inwardly to provide a relatively large eye, said arms then extending downwardly in opposite directions for a distance and one of said arms then bent inwardly and the other of said arms bent upwardly and inwardly to dispose their ends one above the other in overlapping relationship to form a relatively small eye connected with the relatively large eye by a restricted passage, one of said arms having its end bent about the other arm and said other arm having its end upset to form a head whereby while the overlapping end portions of the arms may be moved relatively they may not be separated, said arm having the upset end provided with a notch, and the end portion of the arm bent about the notched arm adapted to be moved into the notch on a strain being placed on the loop whereby to prevent relative movement of the arms.

7. A loop of the class described including an attaching portion, a pair of arms extending from said portion, said arms bent to provide a relatively large and a relatively small eye connected by arestricted portion, said arms at their end portions bent into over-lapping relationship whereby to close one side of the relatively small eye, and locking means between the over-lapping end portions of the arms arranged to become effective to secure them in normal position and prevent spreading apart of the arms and the enlarging of the small eye upon a strain being placed on the loop.

In testimony whereof I affix my signature.
